Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a rotor and water outlet hole groups are used to form granular water, then granular water spray capability is improved, but water flow impact force is diminished resulting in shorter spray distance
Solution Approach 1:
The water outlet structure is segmented into multiple water outlet hole groups arranged concentrically, with each group containing outer and inner water outlet holes. This segmentation allows water flows to interweave and collide, forming granular water particles while maintaining structured flow paths that preserve impact force.
Solution Approach 2:
The invention introduces a vertical dimension to the spray pattern by arranging water outlet holes at different radial distances from the central axis. The outer water outlet holes spray outward while inner holes spray inward, creating a three-dimensional granular water structure that maintains flow momentum and impact force.
2Quantity of substance
If water outlet holes are arranged concentrically with skewed angles, then granular water formation is improved, but spray distance is reduced
Solution Approach 1:
The water outlet holes are arranged asymmetrically with respect to the central axis, with outer holes positioned at larger radial distances and inner holes at smaller distances. The spray angles are skewed relative to the axis, creating an asymmetric granular water pattern that extends the spray distance while maintaining particle formation.
Solution Approach 2:
The invention creates dynamic water flow interactions where outer and inner water flows collide and interweave in a controlled manner. This dynamic interaction forms granular water particles while the overall flow structure maintains forward momentum, extending the spray distance.
3Area of stationary object
If granular water is produced with small particle size, then spray coverage is improved, but massage effect is reduced
Solution Approach 1:
Different regions of the water outlet structure produce different particle characteristics. Outer water outlet holes generate larger particles suitable for massage, while inner holes contribute to finer particles for coverage. This local quality differentiation allows simultaneous achievement of broad coverage and effective massage.
Solution Approach 2:
The concentric arrangement of water outlet hole groups creates a spherical or radially symmetric spray pattern. This curvature in the spray structure allows water particles to be distributed over a wide area while maintaining sufficient particle size and impact force for massage effect through the radial collision and interweaving of flows.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure enhances the shower experience by producing larger water particles with stronger impact force and reduced turbulence, resulting in a more effective massage effect.
Implementation Method 1
When the rotor drives the water outlet nozzle to rotate eccentrically, a centrifugal force generated by the rotating water outlet nozzle throws a water column flowing out of the water flow channel into granular water
Implementation Method 2
the flow straightening piece in the water flow channel reduces turbulence, resulting in the spiral granular water having larger water particles, stronger impact force, and lower temperature drop
